There were a total of three gates to Netherworld Mountain. One was the main gate and the other two were side gates.
However, no matter which gate it was, there was an Eight Trigrams Formation. Ordinary people could not enter at all.
Lu Yan walked through the most secluded door because she didn't want to be caught by the surveillance cameras.
She didn't want to attract attention either. She just wanted to quietly kill her target and leave after breaking the array.
To Lu Yan, killing someone was as simple as breathing.
Not to mention someone like Bai Chang who did not have any martial arts skills, even if it was a former Special Forces soldier, she would still be able to kill him instantly.
Of course, other than her agility and fighting skills, Lu Yan also had a genius brain.
